6 Common Triggers of a Check Engine Light

When a check engine light illuminates, it can certainly be a cause for concern----but this light doesn't always mean that an automotive catastrophe is near. Nevertheless, it's important to play it safe and quickly get to a shop that has advanced computerized diagnostic equipment that can determine the issue promptly, so that you can get back behind the wheel in as little time as possible. Here's a look at six common causes of a check engine light turning on.

Faulty Mass Air Flow Sensor

This monitors incoming air and then calculates how much fuel to inject with it. If it so happens that this is the cause of your check engine light turning on, it won't cost an exorbitant sum to get it remedied.

Failing Catalytic Converter

On the other hand, if this is your problem, it could well cost a fair amount of loot. But it's a repair you'll need to have done because of the role of a catalytic converter, which is to turn carbon monoxide into an emission that is less harmful to the environment.

Faulty Oxygen Sensor

This tracks how much unburned oxygen is in your exhaust system. Problems with your oxygen sensor can subsequently result in decreased fuel-efficiency, as well as problems with your catalytic converter.

Failing Ignition Coil

This is critical to generating the spark needed for your engine to come roaring to life on all cylinders. Ignition coils can go fail due to extreme weather temperatures, but also eventually just from regular wear and tear.

Bad Battery or Charging System

Depending on the particular year that your vehicle was manufactured, this could be the reason that the light is illuminating.

Poorly-Fitting Gas Cap

It might seem strange that this sometimes triggers the light, but it's true. A tightly sealed gas cap is important because it will help to prevent the evaporation of fuel before it gets used.
